Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1,1'-Dipropyl-[4,4'-bipyridine]-1,1'-diium bromide (CAS 52243-87-5), molecular formula C16H22N2Br and molecular weight 322.27 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1,1'-Dipropyl-[4,4'-bipyridine]-1,1'-diium bromide (C16H22N2Br) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
CATO manufactures 1,1'-Dipropyl-[4,4'-bipyridine]-1,1'-diium bromide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
